/Engine/Source/Runtime/Engine/Classes/GameFramework/Actor.h
Returns the point of view of the actor. Note that this doesn't mean the camera, but the 'eyes' of the actor. For example, for a Pawn, this would define the eye height location, and view rotation (which is different from the pawn rotation which has a zeroed pitch component). A camera first person view will typically use this view point. Most traces (weapon, AI) will be done from this view point.
